February experiment – invisible physics

Thursday, February 3rd, 2011

Everyone knows there is carbon dioxide all around us Рwe breath it out all day long Рhere is a  simple experiement to show the invisible physics laws at work!

Materials: glass, carbonated soda (light colored such as ginger ale is best) and a dark colored button.

Process: Fill a glass to about a half inch from the top with the soda. drop in a button. The button may float. Now tap the glass so the button falls to the bottom of the glass. The button will be surrounded by bubbles and rise in the glass.

Reason: This bubbles are carbon dioxide gas ( the same gas breathed out by humans and in by plants) that attach to the bubble and make it rise.
